Which statement is true about leukoplakia?

• A. Lichen planus
• B. Erythroplakia
• C. Candidiasis
• D. Leukoplakia

Answer: (D)

Leukoplakia is defined as a white patch on the oral mucosa that cannot be rubbed off and cannot be explained by any other disease. This makes the statement about leukoplakia true because it captures its essential feature: a persistent white lesion not attributable to another condition. Other white lesions are distinguished by their typical characteristics: lichen planus is an inflammatory condition with a reticular or lacy white pattern; erythroplakia appears as a red patch and has a high risk of dysplasia or malignancy; candidiasis is a fungal infection that forms white plaques that are often removable and accompanied by an underlying erythema. Leukoplakia is also considered premalignant, which is why recognizing it as a distinct, non-explainable white patch matters clinically.
